Which outcome occurs when sediment supply overwhelms a river's capacity around an alluvial fan in a tectonic basin?

💡 Explanation

Channel avulsion occurs to re-establish higher-gradient paths via slope adjustment because increased sediment deposition raises the channel bed. This triggers localized shifts, therefore encouraging steeper gradients, rather than equilibrium or a stable profile.
